Gdday fellas,

I was wondering if someone could give me some specific info on gtr injectors on a rb20det...after putting the injectors in along with the resistor pack...will the car still be driveable? The car is a r32 with exhaust, hks2535, fmic, fuel pump and remapped ecu...

I was hoping to be able to put the injectors in myself and then drive it to my tuner for a dyno tune to run the larger injectors...can someone tell me if the car will be driveable? and if so how bad will it be? cheers...

Maybe. It'll be ultra ultra rich, probably foul your plugs instantly. That is if it starts. From memory, rb20 injectors are 270 cc, so you're going to 440 cc.

It's easy to change injectors. Maybe just bring your tools with you and do it in your tuner's carpark?

You'd be able to drive it... just barely. Even if it starts. You'll flood it. It will run really rich too and would foul your plugs in about 20min after the car is warmed up.

Standard RB20DET from memory like Manhore has said, is about 270CC. GTR ones are somewhere about 440CC. Again like Manhore has said. SO thats a huge step up without a tune. Its really simple to change it all, two 10mil bolts hold the fuel rail on, and just have the resistor pack ready and do it in the car park. push it into the Dyno and simple.

You're risking damage by running that rich, I wouldn't recomend it.

      It only looks tidy, as most of the stuff that was on the whole back wall, is now in the trailer to go to the tip, or has been shoved in my 2.2x2.4m "Spare parts room", and now I can't get to anything in there Ha ha ha I could definitely do with a bit more space, but I'd just end up with your problems I'm going to enclose the car port beside the garage, and move a lot of stuff into it I think. OR... It will be setup as a fabrication area, and the main garage will have parts storage in it. I'm not sure yet... Need some pictures of that big shed you've got with the bikes and Skyline in

      No. I think it's gone. 😭 I think you can get body coloured ones on eBay so I think I'll get one of those... Or just hang a red ribbon from the hole and whack a TOW sticker next to it.

      Cleaning my wheels 😍

      Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.

      @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣

      Modern oils are amazing. Add tyres to that as well.
